摘要
随着CAD制图软件在煤矿的应用,技术人员掌握CAD制图计算钻孔参数的方法很有必要。以某矿煤层进行区域突出危险性预测施工的测压钻孔为例,介绍了CAD制图计算煤巷和石门穿层钻孔参数的方法。
As the application of CAD-drawing software to mine,it is necessary for technical staff to master method of calculating borehole parameters by CAD-drawing.Exemplifing measuring pressure boreholes of a mine seam to forecast dangerousness of regional outburst,this paper illustrates the method of calculating mine roadway and cross-seam hole parameters by CAD-drawing.
